Description

Scriber for English drawing

Technical field

The utility model relates to a kind of English teaching auxiliary appliance, is specifically a kind of scriber for English drawing.

Background technology

The scriber for English drawing used at present comprises positioning rule, lever arm, portable plate and clamping hole, positioning rule is set with the portable plate that can slide, portable plate connects rotary lever arm, lever arm arranges clamping hole, but the length of the line marked is also accurate not, therefore, need to study a kind of educational aid that can draw comparatively accurate four line three lattice of length fast on blackboard.

Utility model content

Technical problem to be solved in the utility model is, overcomes the defect of prior art, provides a kind of energy the disposable scriber for English drawing marking comparatively accurate four line three lattice of length.

For solving the problems of the technologies described above, the utility model proposes a kind of scriber for English drawing, the bottom of positioning rule is provided with the sucker of fixation, positioning rule is set with the portable plate that can slide, portable plate connects lever arm, lever arm is provided with clamping hole, and positioning rule is provided with the size scale arranged along portable plate glide direction, and portable plate is provided with the peep hole for checking size scale.

After adopting said structure, compared with prior art, the utility model has the following advantages: the four line three lattice length that this practicality marks are comparatively accurate, during use, lever arm is turned on, perpendicular to positioning rule, under the drive of portable plate, check according to size scale and by peep hole and disposablely can draw comparatively accurate three lattice four lines of length, easy to use, time saving and energy saving.

As improvement, positioning rule is provided with the positioning baffle for geocoded activity plate, can determine that the original position of ruling makes line more accurate so easily.

As improvement, portable plate arranges the right angle stop being used for restraint arm rotational angle, lever arm can be made like this to keep 90 degree, i.e. the glide direction of lever arm vertical motion plate, thus the angle of line is remained unchanged, more stable.

As improvement, the size scale of the depression that the middle part of positioning rule is provided with, like this, actual when using the wearing and tearing of size scale less.

As improvement, peep hole is equipped with the transparent protective shield preventing impurity from entering, and this avoid impurity and is entered between positioning rule and portable plate by peep hole, thus avoids wearing and tearing.

Detailed description of the invention

Below the utility model is described in further detail:

A kind of scriber for English drawing of the utility model, comprise positioning rule (1), the bottom of positioning rule (1) has been provided with the sucker (7) of fixation, positioning rule (1) is set with the portable plate (3) that can slide, portable plate (3) connects lever arm (2), lever arm (2) is provided with clamping hole (4), positioning rule (1) is provided with the size scale (8) arranged along portable plate (3) glide direction, and portable plate (3) is provided with the peep hole (9) for checking size scale (8).

Portable plate (3) is arranged the right angle stop (5) of restraint arm (2) rotational angle, this stop can the rotational angle of restraint arm (2), when lever arm (2) is closed, parallel with positioning rule (1).

During use; rotate lever arm (2); regulate stop; make lever arm (2) one-tenth 90 degree vertical with positioning rule (1); stop can be arranged to fixing stop; portable plate (3) is moved back original position of directly ruling; i.e. positioning baffle (10) place; the arrow of transparent protective shield (11) projection aims at size scale line (8) zero-bit of the upper depression of positioning rule (1); after determining to need to mark four line three lattice length, the numerical value according to the observation in hole (9) carries out precise scoring lines.

The utility model is not limited to drafting three lattice four line, can arrange the quantity distance of clamping hole (4) as required flexibly.

The above is only better embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in present patent application scope change or modify, and are included in the utility model patent claim.
